Release packaging using automake/autoconf
This program was written by a German university student named Alexander
Lehmann in 1995. He evolved it to a beta
version 0.6 and then dropped off the face of the net. In Fall 1999,
after the program had been stable and in production use for four years,
Greg Roelofs added some minor features and released 0.7.
A short time later, with Greg's consent, I took over maintaining
gif2png in order to give it a proper manual page and release
packaging. Alexander Lehmann is OK with this and has even approved
a change in the license terms to use the libpng/zlib license.
This code was totally stable between 2004 and 2009, so it lay dormant
in a bunch of RCS files for six years before being converted to a more
modern VCS. If you really care about the release dates for all the
ancient versions, you can deduce them by mining the tagged versions.
